MECHANISM FOR BREAKING AND HANDLING STONES- Application filed June 22,1921. Serial No. 479,448.

To all whom it may concern:

Be it known that JAMES REANEY, a citizen of the United States, residingat Ruxton, in the county of Baltimore and State of Maryland, hasinvented certain new and useful Improvements in Mechanism for Breakingand Handlin Stones, of which the following is a speci cation.

This invention relates to an improved machine for breaking and handlingrock andother materialsand has for its main object to provide a machinethat combines a power hammer and a shovel device arranged on aself-propelledvehicle structure whereby it may be portable and whereinthe shovel or hammer may beswiing from one side to the other to bringeither of them into position for operation.

Another object of the invention is to provide an improved means forportably sustaining a power hammer whereby the latter may be capable ofmovement forward or backward with respect to the sustaining means; maybe raised or lowered or be swung laterally to present the hammer atsubstantially a right angle to the surface against which the blow is tobe directed, and A further object of the invention is to provide animproved construction of power iammer.

With these, and other objects in view, the invention is illustrated inthe accompanying drawings, wherein,-

taken on the line 11-11 of In carrying the invention into practical Iefi'ect there is provided in the present instance a vehicle-20, mountedon a portable truck 21, as indicated in Fig. 1 of the drawing. Inpractice, this vehicle has a cab 23,

in which mechanisms are installed for propelling the vehicle andoperating suitable Windlass mechanism and pumps for the compression ofair, inxcase compressed air is utilized as the motive fluid foractuating the hammer devices, or a boiler in case steamis utilized assuch motive fluid. The present machine is especially dewhere a terblasting rock from its bed it is necessary to further break the stoneinto desirable sizes or sizes that can be handled by a pow-eractuaitedshovel or bucket,so it can be loaded onto cars or trucks and conveyed tothe mill where any further reduction in size that may be necessary canbe effected by crushers or other means.

With these objects therefore in view, I mount the vehicle 20 on thetruck 21, so the same can be revolved or swung from one side to theother of the portable truck, and from one side of the vehicle there ispivotally sustained a beam 24, which sustains a suitable shovel orbucket device 25, that may be elevated or lowered under the control ofmechanism in the cab.

At the opposite side, the vehicle is provided with two spaced aparttrack-beams 25 and 26 respectively, which latter extend horizontallyfrom but are rigidly held with respect to the cab. 1

On these track-beams there is mounted a carriage or truck which has twoside plates 27 and 28, that are connected by upper horizontalcross-shafts 29 on the ends of which there are flanged wheels or rollers30. These wheels or rollers 30 aresustained by and are designed to rollupon the top faces of the track-beams so that the weight of the carriageor truck is sustained by said beams.

At the lower edge each of the side plates 27 and 28 of the carriage ortruck is provided with flanged rollers 31, which latter engage the undersides of the track-beams whereby upward displacement of the carriagefrom the beams will be prevented.

Each side plate 27 and 28 of the carriage or truck is provided with acircular boss 32, near its upper edge which forms a trunnion bearing andthese bearings are centrally located with respect to the front and rearends of the side-plates, as clearly shown in Figs: 2 and 3 of thedrawings.

The purpose of the carriage or truck is to sustain the entire hammerdevices, out of these devices an upper fluid motor only 33 is directlyattached to the carriage by means of trunnions 34, which projecthorizontally and enter the bearings of the side plates.

This upper fluid motor 33 hasa cylinder whose head 35 is provided withside lugs 36 at diametrically opposite sides thereof and near thebottom, said cylinder has other side lugs 37 so that'guide tubes 38, mayextend vertically from the upper to the lower side lugs, as shown bestin Figs. 6 and 10 of the drawings, and for a purpose that will presentlybe explained.

In the cylinder of the upper fluid motor 33, there is a piston 39,having a stem 40 which passes through'a stuffing-box 41, and dependsbelow said motor. The lower end of this stem 40 is rigidly connected toa horizontal plate 42, and at opposite sides of the stem this plate hasan upwardly-extending guide-rod 43, which rods pass up through the lowerlugs 37 on the lower end of the motor above and enter the guide tubes38.

It is therefore to be understood that when the piston 39 is operated tomove the stem 40 in a vertical direction the horizontal plate 42 will begiven a like movement and the guide rods 43, will prevent the plate fromturning during such movement.

The upper motor 33, its piston 39 and stem 40, are not utilized, in thisinstance, to give a hammer-blow, but are merely used to raise or lowerthe hammer devices to properly position said latter devices with latterserves as a cover for the cylinder, and

that said cylinder has a piston 45, and a rod 46, that depends from thelower end of the cylinder.

mer-head and has a central. depending hammer-lug 48.

The hammer-head 47, is provided with a plurality of vertical holes orpassages 49, as best illustrated in Figs. 8 and 9 of the drawingswherein it will be seen that four of such passages are provided. Througheach of theie vertical passages there extends a bolt 50, whose upper endis provided with a head 51 and whose lower end is bolted to ananvil-plate 52,a washer 53, preferably being interposed between theanvilplate and the hammer-head and the bolts 50 extending freelytherethrough.

A coiled spring 54 encircles each vertical bolt 50 and has its lower endseated on top of the washer 53 and its upper end seated against theunder side of the bolt-head 51, so that the washer and plate 52 areyieldingly held together by the four springs 54. 1

While the springs 54 yieldingly hold the anvil-plate 52 and washer 53together, they play no part in sustaining the anvil-plate in position toreceive the blow of the han'nnerlug 48. The means for thus holding theanvil-plate will therefore now be explained, reference being made toFigs. 3, 7 and 9 of the drawings.

The lower cylinder 44, carries a plurality of depending rods 55, whoseupper ends are rigidly secured in the lower end of such cylinder andextend downwardly therefrom. These rods are therefor rigid with the cyl-This rod 45 carries a head 47 at its lower end WlllCll in reality is thehamllll inder and, while movable therewith, have no I q movementindependently thereof.

' now be explained, reference being made par- These rods 55, extendfreely through vertical passages 56 in the hammer-head 47, and theirlower ends are reduced in diameter whereby to form shoulders 57 thereon.These reduced ends of the rods extend through perforations 58, in thewasher 53 while the shoulders 57, seat on top of said washer so that thewasher can have no vertical movement independently of the rods. Nuts 59,are screwed onto the lower reduced ends of the rods 55, and seat againstthe under side of the washer so as'to rigidly engage the washer withsaid rods.

In order to permit the anvil-plate 52,'to

seat close against the under side of the washer 53, the same is providedwith suitable sockets or recesses 60, which receive the nuts 59 on thelower ends of the rods, as clearly shown in Figs. 7 of the drawing.

The washer 53, is provided with a central hole 61, through which thehammen-lu 48,

may project to stroke anvil-plate:

the upper side 0 the The anvil-plate 52, has a pointed projection orother shaped working-edge 62, which directly engages or contacts withthe rock to be broken.

From the foregoing explanationit will. be understood that the uppercylinder 33is pivotally sustained from the carriage or truck by thetrunnions 34 and that its lower end, and also the cylinder 44 and thehammering mechanism caried by the latter,

hang pendantly from said carriage.

The carriage, because of its rollers 30-31 and the track-beams 25 and26, may be moved on the track-beams in a direction toward or from thecab 23 so that the hammer mechanism may be moved more or less laterallyor to one side of the trackrails 22. To efiect this, mechanism isprovided whereby the movement may be accomplished with ease andexpedition, as will ticularly to Figs. 2, 6, 12, and 13 of the drawings.

By reference to Fig. 2, it will be noted I that a horizontal shaft 63extends along the chain 66, passes.

inner side of track-beam 26 and has its outer end supported in a bearing64, and -is carried on said beam. This shaft 63, extends into the cab 23and on the interior of the latter said shaft carries a driving elementsuch as a sprocket wheel 65, over which a This chain 66, alsov travelsover a sprocket 67 which is carried on a main driving-shaft 68, and aclutch 69, havin a lever 70, is so connected with the sproc et 67, thatthe latter may be connected with or disconnected from the saiddriving-shaft 68 at will. The shaft 63, is circumferentially'-screw-'threaded along its stretchbctween the cab and the outer bearing 64,. andthisfscrewthreaded portion extends along and close to the vertical sideplate 28 of the carriage or truck, as clearly shown in Figs. 2 and 13 of'the drawings. This side. plate 28 of the carriage. or truck sustains as lit or twopart bearing-bracket 71, which is internally screw-threadedso as to engage the threads on the exterior of the shaft.

Obviously, as shaft 63 has no longitudinal movement while the threadedbearing 71 is movable with the carriage or truck, when 'sald shaft isrevolved the bearing 71 will be 'made to travel thereon, thereby movingthe carriage in the direction in Which said bear ing is caused totravel. Obviously if shaft 68, be capable of reversal in its directionof rotation 1 it may drive the sprockets and chain in either directionand thus enable the shaft 63 to be rotated in either direction so thatthe carriage and the suspended hammering mechanism may be moved eitherforward or backward on the track-beams.

In addition to the back or forward adjustment of "the carriage andhammermechanism with respect to the cab, it is also desirable that saidhammer-mechanism be capable of being swung with respect to the carriagefrom which it is suspended in order that the blow may be delivered at aright angle with respect to the surface 7 against which it is to bedirected.

T 0 provide for this swinging adjustment of the hammer-mechanismlpendantly sustain the latter by the trunnions 34 but the means employedto effect this swinging adjustment will now be explained, particuloweredge of this plate 73, is provided with a segment-rack 74, which lattermeshes with a Worm 7 5, that is carried on a long horizontal'shaft 76. vj

This horizontal shaft 7 6; as canfbe seen in Fig. 2 of'the' drawing,extends horizontally at the inner side of the side plate 27' of thecarriage'ortruck with jits' forward end seated in a bearing? 7 on acrossbar--78- at the outer endsv of. and con two track-beams.

This shaft 76-extends toward and enters t ng, the

the cab 23 and carries a sprocket 79 over which a chain 80 passes. Thischain also extends around a' sprocket '81 on the main driving shaft 68,and a clutch device 82, controlled by a lever 83, serves to connect ordisconnect the shafts 68' and 76.

The shaft 76, passes through suitable guide bearin s 84, which arecarried at the inner side oi the vertical truck or carriage plate 27which bearings are located at opposite ends of the worm 75, and saidshaft is provided with a groove 85 which extends longitudinally thereofand .a key in the worm 7 5, engages the groove of said shaft and coactstherewith whereby to form a spline and feather connection which willpermit the shaft 76 to be revolved so. as to revolve the worm and swingthe segmentplate 7 3, which latter will rock the trunnion 72-34, andthereby swing the cylinder 33 in a direction corresponding to thedirection in which the segment-plate is swung by the shaft. Obviously,when the cylinder 33 is swung the lower cylinder 44 and hammeringmechanism will be correspondingly moved.

To raise or lower the hammering mechanism it is only necessary toactuate the pis ton -39 .in the cylinder 33 in the desireddirection,connections 86 and 87 for the inlet or exhaust of theactuating medium, such as a fluid under pressure being provided in thecylinder.

To actuate the hammering mechanism, fluid pressure connections 88' and89 are provided in the lower cylinder 44.

From .the foregoing explanation it is to be understood that the vehiclecarrying the shovel and hammer structures maybe moved along thetrack-rails to any precise point desired; that the vehicle may berevolved on plate 52 may be seated on the material to be broken and thehammer-head reciprocated to deliver blows against the anvil-plate.

Having described my invention, I claim 1. In a device of the characterdescribed the combination with a trackwa a carriage on the trackway, acylinder lvotally carried by the carriage and depending from the latjter, power means for inclining the cylinder with respect to thecarriage, a piston in said cylinder, a power hammer sustained by saidpiston and means independent of said piston for actuatin saidhammer.
